The embodiment of the invention illustrated by these drawings is a sound-reproducing instrument or graphophone whereby any selected one of a plurality of circular disk records of different diameters may be tansferred to the graphophones turntable and played thereon, or either selected side of a double record may be played, whereupon the record disk is returned to its original position in a rack or holder, such seleczontal top 2 and a platform 3 parallel therewith l and rotatable in alternately opposite directions on supporting rolls 4 about a vertical axis concentric with th record-carrying turntable 5.

Excepting for the driving motor and its connections and the record-holding rack designated generally B, this platform carriesA the operating mechanism and devices, some of which are supported above the platform and others suspended j below it extending downwardly through a circular opening 1 in the top 2 of the frame. The side 8 of this opening forms a circular track for the platforms rollers 9 which assist in maintaining the platform in axially vertical rotative position.

This platform and all the parts carried thereby may be lifted and removed entirely from the base or frame of the structure (for making repairs and replacements or otherpurposes), the

machines vertical main shaft I0 being removably seated in a socket I I in the upper end of its coaxial driving shaft I2 (rotated as by an electric motor indicated at I4 inFigure 31), this shaft III being turnable in said socket against a spring- 4pressed member I3 engaging its flattened side, in case a stoppage occurs in the driven mechanism. The turntable is keyed at I8 to a shaft I1 aligned with the main shaft I0, and a circular box I9 contains a coiled flat spring I5 whose inner end is fastened at I6 to said shaft I1 and whose outer end frictionally contacts the curved inner side 20 A of the box which is secured at 2| to main shaft I IJ. Thus the turntable is yieldingly driven by this main shaft. 'Ihe rack or record holder mounted on the top 2 of the structure and indicated generally 6 (to be particularly described hereinafter) is adapted to contain side by side and edge up a plurality 'of disk records 22, ex-

tending in the turntables radial directions. Record-transferring mechanism mounted on'l the platform 3, and hereinafter particularly vdescribed, is brought by rotating the platform, into registration with the particular record (in the rack) selected for playing, the particular record side (of a double record) selected for playing being governed by the rotation of the platformin one direction or the other. This platform is rotated for this purpose by the following mechanism, referring now to Figures 1, 2, 3, 4: A shaft 23 has teeth forming a pinion 40 near its outer end meshing with a, continuously toothed endless rack 24 mounted on the downwardly extending bracket 25 which is secured to the structures top 2 and is curved in a'horlzontal plane concentrically with the platforms axis of rotation.

The teeth of this rack extend (as seenin Figure 1) along its opposite (upper and lower) sides, for'rotating the platform in opposite directions, and around the end portions connecting said sides. Said shaft 23 bears turnably and also laterally-slidably in a vertical slot 26 through the downwardly extending arm 2 of the platform 3. As shown in Fig. 1 the rack 24 is centrally mounted in an oblong recess 25a. formed in the face of the stationary bracket 25; and the shaft 23 has a reduced end portion 23a. which remains in contact with the walls of the recess and thus holds the teeth of the pinion 40 in mesh with the teeth of the rack. This causes the pinion 4I) to travel around on the rack as the shaft 23 is rotated, and

move the platform back and forth through the' vconnection of the depending arm 21, secured to the turntab1e,'in which the shaft is vertically guided. To render this shaft suiciently exible, its inner end has a head 28 through whose angularly spaced bores 29 slidably bear the pins 30 projecting from the side of a gear 3l meshing with and driven by a gear 32 on shaft 33 carrying the bevel gear 34 meshing with and driven by the gear 35 on the main shaft III. The head 28 and gear 3I are pressed apart by springs coiled around the pins 38.

The clutch. members 35, 31 on shaft 33 (see Figure 5) being engaged, the platform 3 is oscillated by the main shaft III in alternately opposite directions (depending on whether the gear 40 of shaft 23 is meshing with the teeth of the upper or the lower side of the lrack 24 at the time) unti stopped in registration with the particular record (or the particular side thereof) in the record rack which has been selected for playing. This stopping of the platforms turning movement iseffected by the following mechanism:

.Y The gear 3| (see Figure 1) meshes with and epesses mechanism includes the followingparts operating in the following manner:

The particular trigger corresponding to the selected record disk (or the selected side thereof) is moved from its position shown in solid lines to that seen in` dotted lines (Figure 8) wherein it is engaged by the lug 41 of the corresponding disk 68 and is thereby moved against the pressure of a spring 98 downwardly and outwardly (and out k of such enga-gement) by the camming action of its inclined inner edge 5| on'the horizontal rod 52, whereupon spring 98 raises the` trigger to its .original (solid line) position. The triggers are selectively moved to their dotted line positions (for engagement with the lugs 4 1) by suitable selecting means.

Such means in the illustrated construction coinprises electromagnets 53, 531 (one. magnet for each trigger) whose armature levers 54, fulcrumed on a horizontal rod 58, are connected by llinks 55 to the triggers respectively (Figures 8 and 10) whose magnets are in electric circuits 56 respectively having switches or buttons 51 for opening and closing the same (Figure 31) These triggers straddle at 53 the horizontal vrod 60 (being held apart by spacers 6|) carried bye-one arm 62 of a lever fulcrumed at 64, so that when any trigger is forced downwardly by the engaging lug 41, it swings this arm' and the levers parallel other arm 66 down against the pressure of spring 65, thus carrying the double-sided catch 61 (pivoted at 68. on arm'G) downwardly far enough to permit spring 10 to turn the upper end of this catchs middle' portion 1| into a position beneath the free end of a lever arm 12 (as seen in Figure 5), whereupon spring 65 raises arm 66 and catch 61 and lifts arm 12, thus releasingits shoulder 13 from the upwardly extending part 14 ofy a horizontal bar 15 slidably mounted at 16 on another slidable horizontal bar 11. Thus released, bar 15 is slid by its spring 18l toward the right hand side of Figures 1, 5 and 6 causing its inclined right hand end 13 to cam'on the under edge of a lever catch whose other end 8| has been engaging the lower endfcf a lever 82 fulcrumed at 83 and having a fork 84 connected with clutch member 36. The spring instantly swings lever 82 to the position shown in Figure 5 disengaging 'the clutch members 36, 31 and stopping lthe rotation of the platform 3 in the position wherein the record-transferring mechanism thereon stops in registration with the disk record in the rack selected for playing. 'Ihe parts are now in position for the record-transferring mechanism to .transfer the selected record from the rack to 1 playing position on the turntable.

This mechanism is as follows and is operated in the following manner and by the following means:

The said movement oi' lever 82- draws the inclined portion 86 of a horizontal b'ar 31 (corinected at 68 to this lever) from supporting engagement with 44a pin 33 on a vertically movable bar 30 thus permitting this bar to fall tothe posi'- tion seen in Figure 5 wherein its fork 3| connected to clutch member 32 causes it to engage .clutch member 33 of an idler gear 34 on the main shaft l0.

It will be seen that clutch members V38, 31 cannot engage. while clutch members 32, 33 are in engagement. The gear 34 meshes with gear 35 on a vertical shaft 36 having the gear 31 of a composite element comprising cam disks shown in Figures 11, 12, 16, 19 and 23, .and in assembled side by side position in Figures 1 and 2 in which assembled position they are pinned together at |00 and rotate as one element about an upstanding hollow post 331 on the platform 3 in which post' the turntable's shaft I1. rotates.

For the playing of each record these cam disks make one complete revolution, during a part of which the transferring mechanism is operated thereby to4 transfer a record to the turntable and, after an inoperative interval (while the record is being played), said mechanism is operated reversely by the rotating disks to return the record from the turntable to its position in the rack. To accomplish these ends, the cam disks (turningA in the direction indicated by curved arrows) have the following parts operating the following connections and in the following manner:Y

The lowest (the toothed) eammsk es (see Figures 2, 19 and 20) has in its under side a cam extension |05 of platform 31s mounted 'the record gripping jaws and certain operating parts therefor. The uppermost cam disk |06 (see Figures 2,

'11 and 12) has a roller |01 which travels in a cam groove |08 inthe plate |03 fastened to the under side of another Wide iiat bar ||0 (slidable relatively to and paralleliy with bar |03) whose post bears in'a slot ||2 of bar H0, ascrew post ||3 of the platform 3 bearing in slot I4 of bar l I0 in the relative sliding movement of these bars This upper bar*l ||0 carries at its outer end a toothed rack 5 vvertically yieldingly mounted on a threaded post I6 surrounded by a spring I |1 whose tension is adjusted by the posts nut ||8. On the outer end of the upward extension |05 of the platform 3 are spaced ears |2| having aligned bearings |20 in which a hollow member H3 is -turnable through about degrees. (See Figures 1, 11, 12, 13, 14, 15, 27 and 28). This hollow member I3 has a gear |22 with which the toothed rack H6 meshes to turn it, and carries between said earsa hollow member |21 turnably mounted at |23 about an axis transverse to the axis of member ||3. This hollow member |21 has at its outer end spaced arms |24 on which the recordfgripping jaws |25 are pivotaily mounted at |26 respectively.

A rod |28 is slidable in this hollow member |21 so that its conical outer end presses between and separates (against the pressure o'f springs I 23) the'inner arms of said jaws to press their outer arms |30 into gripping engagement with a record disk therebetween. This rod |23 has diagonal teeth |3| with which mesh the diagonal teeth |32 of a rod |33 slidable in hollow member I3, so that the sliding movement-of rod |33 moves rod .|23 radially inwardly or outwardly. The movement of roller |01 in cam groove |08 of bar ||0 (see Figures 11 and 12) slides this bar and by its rack (meshing with gear |22 of hollow member III) turns the said member and the separated gripping iaw's from the position seen in Figures 13 1 and 11 and in solid lines in Figure 15 to 'the position shown in dotted lines in Figure 15, wherein they straddle the selected record disk 221 in the rack. The roller |01 now passes out of cam groove |08 so that bar |I0 remains stationary, and immediately the turning. of cam disk |06 vbrings the rise |39 of its peripheral cam |40 to the inturned'end 4| of a lever |42 fulcrumed at |43 on the upward extension |05 of platform 3 and moves the leaf spring |44 at the opposite end of this lever into pressing engagement with the end of rod |33 and yieldingly slides it against the pressure of a spring |34 thus causing rod |28 to slide outwardly and press the gripper jaws end portions |30 on the record disk between them. The roller |01 now passing into the opposite end of its cam groove |08 slides bar l0 inwardly so that its rack rotates the hollow member ||9 selected for playing is turned upwardly in its passage from the rack to the turntable, and by the following mechanism:

The hollow member |21 has a gear or toothed sector |45 (see Figures 14, 27 and 28) which is brought into mesh with one or the other of a pair of inwardly-facing spaced-apart toothed sectors |46, 41 on the spaced sides |48, |49 respectively of a member |50 bearing slidably on the ears |2|, so that when sector |46 is by the sliding movement of ',member |50 brought into mesh with sector |45 the hollow member |21 is turned in one direction, but when sector |41 is moved into mesh with sector |45 said hollow member is turned in the opposite direction, during the transferring movement of the record disk. The sector |45 is brought into mesh with sectors |46, 41 respectively by the following means:

The top 2 of the structure has angularly spaced threaded stops |5|, |52 marking the limits of the oscillation of the platform 3. On the upward extension |05 of platform 3 is pivotally mounted at |53 a catch |54 whose swinging movement is limited by screw stops |55. (See Figure 13.) A

spring |56 extending between this catch and the member |50 causes said member to slide one way or the other depending on which way the catch is turned on its pivot |53. If the platform 3 be turning toward stop |5| or |52 when the selection of the record-'side to be played is made, one

.of the catchs extensions |51 will strike that stop and turn or trip catch |54 sc as to slide member |50 in the direction which will turn hollow member |21 inthe right direction to deposit the record disk on the turntable withv its selected side up in position for playing. I

I mmediately the record has been transferred to the turntable for playing, the tone arm |58 is moved to engage its needle or stylus |59 in the beginning of the records groove. (See Figures 1, 11, 16, and 23.) The tone arm is mounted. on platform 3 turnably about a vertical axis vconcentric with its supporting member |60, said member having a radial arm |6I. The tone arm is also movable vertically a sumcient distance to raise the stylus from the record disk and to lower stylus in the record groove, and also may be swung vertically to a slight degree to lower the stylus' into said groove at the beginning of the playing and to raise the same therefrom at the end of the playing of the record. (See Figures 16 and 23.) AThe inner end of this lever |65 is normally held in lowered position (to raise the stylus) by the travel of its roller |69 on the long dwell |10 of a cam disk |1| (see Figure 18) fastened on f the under side .of the cam disk |06, but is permitted to rise `(to lower the stylus) by thel passing `of this roller into the ,dip |13 of cam disk 1|.

The lever |65 is connected to arm |6| of the tonev arm by a bar |14 pivoted at |15 on this lever |65 and at |16 on arm |6I, so as to have (in case a large-diameter record disk is being played as hereinafter described) a. slight-horizontal movement relatively to its said connected parts. As shown in Figures l and 17 this bar |14 at its outer end bears on the convex portion |18 of the vertically adjustable pivot post |16 to hold the tone arm raised. i

Mechanism ls provided whereby the graphephone is adapted to` play record disks of different diameters, such as the ten-inch and the twelve-inch records seen in Figure 15, and to lower the stylus into the beginning of the groove of the record disk (of whichever diameter) on the turntable, which mechanism is described and operates as follows:

When the smaller-diameter (ten-inch) record disk is played, the lever |65 and bar |14 swing together as one; but when the larger-diameter (twelve-inch) record disk is laid on the turntable to be played, its edge extending beyond the edge of the turntable (as shown in dotted lines in Figure 17) contacts the upper end of a post |19 carried by the lever arm |80 pivoted at |8| on lever |65 and presses this lever arm downwardly. The leg |82 of arm |80 thus contacts the short arm|83 of a. latch |84 loosely mounted at |85on the under side of bar |14 moving said short arm below and out of holding abutment with a stop |86 on the under side of lever |65. Asa result of this operation the lever |65 is swung by the travel of roller |64 in groove |63 without swinging the bar |14 with it (and without turning the tone arm from its outermost position), this bar |14 turning o'n its pivotal connections |15, |16 until the upward projection |81 -of lever |65 strikes the edge |88 of bar |14, whereupon the lever |65 and bar |14 swing together and the tone arm is swung thereby to a positionl in which the stylus is over the beginning of the groove of the large diameter record and ready to be lowered thereunto. It will be seen thatby this mechanism the stylus is in vlowering position at a greater radial distance from `the turntables axis for a large-diameter record A spring |89 mounted at |90 on lever |65 and at |9| on bar |14 urges them to parallel position. The stylus being now lowered into the outer end of the groove of the record disk (of either diameter) by the riding of roller |69 up into dip |13, and the rotation of the cam disks (including cam disk |62) ceasing, the record is played and roller |64 moves inwardly (towardl shaft |1) in the enlarged dwell |92 of cam groove |63. When the cam disk |62 was rotating before the playing of the record, its peripheral cam 22| engaged the arm 222 of a bell crank lever 223 fulcrumed at 224 in a block 2|9 on the platform 3 (see Figures 75 92, 93 (see Figure 31, etc.) .and causing the rota.-

2, 16, 23,-24, and The other arm 225 of this lever connected at 226 to a member 2|1 has thus slid said member downwardly (againstl spring 232) in its bearing in said block so that the end vmember 2|1 and said end of rod 206 with it, thus raising rod 2|5 and disengaging clutch members tion of the cam disksl to cease during the playing of the record. As the tone arm is. turned, its

This arm |95 has a downward tongue |96 adaptedA to bear in the vertical movement of said arm on the downward extension |98 of arm |93, and arm the end of a screw 200 lthreaded for adjustment in the arm 20| of a bell crank lever 202 whose other arm 203 .engages between stops 204, 205 of the long horizontally slldable rod 206; but if the stylus groove of the record being played terminates undulately in the middle of therrecord, the tongue |96 of arm 95` rides up an incline 201 (raising this arm) and slips over the ratchet teeth 208 of a horizontal bar 209 on the arm 2|0 of another bell crank lever 2|| whose other arm 2|2 also engages between the stops 204, 205.

InV either case, the 'lever arms 20|, 2|0 are thus swung from eachother against the pressure oi the aforesaid spring 2|3, the other lever arms 203,

2 |2 being thus moved into engagement with stop 204 and lcausing rod 206 to slide toward the left hand side of Figures 11, 16 and 23. By this movement the end portion 220 of long rod 206,

(which during the playing of the record has been supporting the vertical rod 2|5 in raised position,

see Figures 31, 28; 24 and 25), is withdrawn fromthe keeper hole 2|6 and falls in a vertical slot 2 8 until 'it rests on the bottom of this slot. 'Ihus the vertical rod 2|5 is permitted '(at the end of playing the record) to fall and in so doing swings downwardly the connected arm 221 of a shaft 220 (see Figures' 3l, 16, 2 and 1) and also this shafts other arm 229 whose wrist pin 230 turns This vertida bar sui ns a slot 23| in which.

wrist pin 230 moves, to permit the unclutching of these clutch members 92, 93 although arm 229 may be in the position seen in Figure 5. The bar 90, rods 2|5, 206 and member "2|1 being in lowered position wherein said clutch members 92, 93 engage to rotate the cam disk, the rod 206 resting` on the bottom of slot 2 I8 is slid (as above described) into keeper hole 2|6 by the spring 2| 3 swingingthe bell crank levers 202,? 2li (see Figure 31, etc).1 These rods 2|5, 206, member 2|] and bar l90 are raised to the position seen in Figure 3l (thus disengaging clutch members 82, 93) by the aforesaid spring '232 surrounding an adjustable screw post 233 and bearing on block 2|9. The rotation of toothed disk 98 causes the cam 234 on its under side to engage and press downwardly the arm 231 of a. lever 235 travelling in a groove 235, whose other-arm is pivoted t0 a vertical bar 238 (see Figures 19, 20, 21 and 1) and thus raises this bars lower end from the keeper notch 239 of horizontal bar 11 against the pressure of spring 240 (see Figures 1, 5 and 6). Thus released, this bar 11 is slid toward theright hand side of Figures 1, 5 and 6 by a spring 241.

By this action lever catch moves from its posil tion seen in Figure 5 and its end 8| moves into engagement with the lower end of lever 82, and

theleit hand end 248 of arm 12 falls into engagement with the middle or web portion 1| of catch 61, and also the shoulder 13 of arm 12 falls into engagement with the upright extension 14 of bar 15. Thereupon the arm 24| of a vertical shaft 242 strikes the adjustable stop 243 carried by bar 11 and slides this bar toward the left hand side of Figures 1, 5 and 6, thereby turning the catch 61 and the lever 82 and moving the bar 15 to their positions seen' in Figure 1 and causing the clutch4 members 36, 31 toA engage, and also slidingbar 81 toward the left ,hand so that its inclined portion 89 disengages clutch members 92, 93.

In this left hand movement of bar 11, the horizontal bar 15 moving with it, -tensions springs- 18 and 241, and the vertical bar 233 drops into notch 239 of bar 11. The vertical shaft 242 is turned (to cause its arm 24| to strike and slide the bar 11) by the toothed cam disk 98 meshing with said shafts gear 244.

The playing of a record may be stopped at any time by closing the button switch 250 in the electric circuit 25| containing a magnet 252 which, when energized, swings armature lever 2|| to move rod 206 toward the left hand to thus allow clutch members 92, 93 to engage and cause the cam disks to rotate and return the tone arm and the record from the turntable to the rack (Figure 31). The circuit 253 to the motor |4 is opened and closed by a master'switch 254.

'I'he means for selecting therecord (or recordside thereof) desired to be played, may manifestly be operated or controlled otherwise than by the means shown', as by coin-operated mechanism and the like. 'I'he armature levers 54 may be yieldingly held in swung positionby suitable means, as the pivoted arms 255 whose notches 256 receive their pins 251 (Figure 8).

Any number of records may be selected at the same time for playing by closing the circuits 56 (by their button switches 51), and the records thus selected will be. played in the order in which the lugs 41 corresponding thereto engage (by the turning of shaft 43) the corresponding triggers 48 respectively to operate the machine.

VAsv seen in Figures 1, 5, 7, 8 and 10, the means for thus playing such selected records successively includes a horizontal bar 210 can-led on the arms 21| of a. lever fulcrumed at 212'and having an- Vother arm 213 engaging the lower arm 214 of a lever iulcrumed at 215 whosel upper arm 216 the motor |4 (seeFlgures 1 and 31).

master switch 254 to operate the motor, and the button switches 51 corresponding Ito the records selected for playing being also closed, the action of the machine as hereinbefore explained causes the energized magnet l53, or 531 (corresponding to one of selected records) to swing its armature lever 54 to the dotted line position seen in Figure 8 whereupon the rotation of shaft 43 causes the corresponding lug 41 to engage its trigger 48 to initiateA the playing of said record, this rst record to be played thus corresponding tothe first one` of the lugs which by the turning of shaft 43 is brought into operative engagement with its trigger.

In the armature levers movement to dotted line position (Figure 8) it contacts the horizontal bar 210 (which extends along all the armature levers in the same relation therewith) and thus swings a'rm 21| toward the dotted line position seen in Figure 8 and the other arm 213 toward the right hand side of Figure 1. 'Ihis action swings lever arm`214 and thereby the mercury switch 218 'to' closed position, thus closing the main circuit 253 containing the motor (this cir,- cuits master switch 254 being already closed).

The same movement of lever arm 213 carries its horizontal link 219 in thev same direction, moving this' links stop .280 so that the lever arm 61 may turn from its position shown in Figure 1 to that seen in Figure 5, and so that the actions hereinbefore described may follow in the playing of the record.

The 'rst one of the series of selected records having been played, the others so selected are (as above stated) played successively and in the order in which the lugs 41 corresponding thereto are brought by the rotation of shaft 43 into engagement with their triggers 48 respectively.

'I'he operating parts 61, 12, 15, etc. remain in the position shown in Figure during the playingof all the records thus selected; and when the playing of the last one of said series is completed,l

engages all .the armature levers 54V in their solid line position shown in vthat view. These arma-A ture levers maybe locked in that position by a horizontal bar 282 engaging them and carriedby the arms 283 of a lever fulcrumed at 284 whose other arm 285 may be locked by suitable means to the part 286 (see Figures 1 -and 10).

'I'he record disks 22 (of larger and smaller diameters) are held in the rack designated'gener- K ally 6 with their central holes in registry vwith each other. This rack, as shown in Figure 29, comprises a plurality of compartmentsone for each record disk-formed by spaced uprightA lplates 260, 26|.receiving the record disk therebetween.

l i A horizontally disposed recordhsupporting member 262 is moved in its longitudinal direction through the hole-263 in one (260) .of said inserted, the record engages the opposite end p (which is a spring268) and presses this rock member or lever 265 to move the supporting member 262 through the holes 263 and 264 as seen in the two left hand compartments in this view, thus supporting the records, with their holes 264 in a level line curved concentrically about the turntables axis.

As the upper bar H0 is forced radially out- `wardly its lug 282 (Figures 19, 20) engages the collar 283 sliding on the rod 284 and compresses a coiled spring 285; and as said bar is forced inwardly said lug engages the sliding collar 286 and compresses coiled spring 281; so that in either case this bar when permitted to return tomedial position is assisted in such movement by the compressed spring.
